To all who/m," 'it may concern:

Be it known that I, CHARLES S. GBANNIS, a citizen of the United States, and resident of Syracuse, in the county of Ononda a, in the State of New York, have invente new 'and useful Improvements in Adjustable AShaft-Hanger Attachments to Girders, of which the following, taken in connection with the accompanying drawings, is a full, clear, and eXac't description.

This invention ertains to well known hangers employed 1n manufacturing establishments for supporting the line-shafting and counter-shafts.

The main object of the present invention is to provide simple, eii'cient and inexpensive means for conveniently attaching a shaftlhanger to the well known ianged iron girders, more particularly to a so called I-beam, commonly used in building construction.

To that 'end the inventlon resides essentially in the combination with a flangedgirder, of a shaft-hanger attachment comprising a suspender provided with means for clamplng it adjustably tothe flanges ofthe girder, and means detachably connecting the hanger to the suspender. y

Furthermore the invention resides in certain novel details in the construction of the attachment as hereinafter fully described and set forth in the claims.

In the accompanying drawings illustrates a side view of a shaft-hanger secured to the girder by the suspension device embodying my invention; Fig. 2 is an edge view of the hanger, with the girder and device shown in section ;\.Fi0. 3 1s a longitudinal sectional view taken through the web of the girder to illustrate more clearly the arrangement of the clamping means; Fig. is a perspective View of the hanger suspension plate; and Figs. 5 and 16 are etail perspective views of a clamping-clip and its attaching bolt respectively. i

Like characters of reference indicate like parts in the several views of the drawings.

denotes a portion of an iron irder formed with horizontal bottom anges #-B-B- and known as an 'Lbeam commonlv used in building construction.

denotes the well known hanger for supporting a linefshaftora countershaft represented at Dv-43,. said hanger bein formed at its top with-the usual horizonta bearing-portions -D-D- provided with -op osite sideA edge 1s provided' with a Figure 1- vertical apertures for the reception of bolts -FF-. It is well known that it has been the usual practice to apply said bolts to wooden beams or other objects for sustaining the hanger. V

The purpose of my invention is to securely fasten the shaft-hanger to the irder shown by suspension means which wil not necessitate a change in the construction of the hanger, and will lpermit the latter to be shifted lengthwise of the girder if required. The form of hanger-attachment which I prefer to use comprises a rectan ular castmetal plate -1 applied to the lottom of v and by which the hanger --C- is rigidly'suspended from the girder. This s11spension-plate-1 has one of its sides projecting beyond the corresponding flange -B- of the girder and is provided at the edges with means for clamplng it to the said ianges. The opposite side of the plate is preferably flush with the flan e. To effect this clampin I form the projecting side edge of the p ate with the 'gld jaw -Qfconsist' ward y projecting lip formed with a longitudinal groove 3'- shaped in cross-section to embrace the adjacent flange -B-. 'Ihe u.- ra ity of detachable and `adjustable jlziws 1l- 4- composed preferably of steel. I refer to employ two' pairs of these jaws isposed at the respective ends of the plate as shown in Figs. 1 and 3. Said jaws +4.- embrace the adjacent flange and plate and each is formed with divergent gripping faces -5- and -6`- to conform respectively to the top of the. flange and an undercut wedging surface -7- as clearly illustrated in Fig;4 2. Eachjaw ll-f is provided with a plain transverse aperture 8- for the lreception of a tap-bolt -9 screwed into the edge of the plate. -.It will be seen that by tightening the bolts -9-,

the jaws -4r-4- and jaw 2- will secure clamp the suspension-plate 1- to the anges, and by loosening the bolts the plate can be readily shifted longitudinally thereon and at the same time the said plate can be' easily and conveniently detached when required.

To connect the hanger -C- to the plate 1- I provide the end portion of said plate with plain vertical apertures -10-10- which coincide with the apertures -E-E- the edge of ng of an up Patented Aug. 9, 1910.

in the top bearing-portions D-D- of the hanger, through which` apertures the aforesaid bolts -F-F- pass, it being understood that the apertures -E-EH are elongated as usual to facilitate the entering of said bolts therethrough. At each aperture 10- the upper face of the late is provided with a recess -11 shape correspondingly with the head `-12- of the bolt -F- to lock the latter against rotation in applying thereto the nut .13- Which engages the bottom of the bearing portion -D- of the hanger as clearly illustrated in Figs. 2 and 4. It will be observed that the shaft-hanger may be easily and conveniently taken down by simply removing the nuts -l3--13-.

While I prefer to employ a, plurality of detachable jaws 4- arranged as shown, at the same time it will be understood that in some instances I may use a single jaw' extending the full length of the suspensionplate -1- and provided with two or more clamping bolts.

Having described my invention what Ik claim is :h

l. In combination with a girdex, a shafthanger attachment comprising a plate extendlng alon the bottom of the girder and provided wit jaws for clamping it to op posite sides of the girder, and han er-connectin bolts passing through the p ate in-` depen ently o the said girder as set forth.

2. In combination with a. girder, a shafthanger attachment comprisin a plate extending alongthe bottom of t e girder and formed with a jaw engaging one side of the gir-der, a detachable jaw on the plate for engaging the opposite side of the girder, a clamping-bo t extending horizontally through the detachable jaw and entering ythe heads seated in the said recesses as set forth.

4. In combination with a girder formed with two opposite horizontal bottom flanges, a shaft-hanger attachment comprisinor a rectan ular plate extending along the Iiottoln of t e girder, and projecting at one side edge beyond one of the flanges, said projecting portion being formed with a jaw consisting of an upwardly projecting lip provided with a longitudinal roove receiving the adjacent flange, detacha le jaws embracing the opposite side edge and corresponding fiange, clamping-bolts passing horizontally throurh the detachable jaws and screwed into the plate, said jaws each formed with divergent gripping-faces to conform to the top of the flange and an undercut wedging surface on the late, theplate being provided with vertica apertures, and havmg its top face provided With recesses at the apertures, and hanger-connecting bolts passing through said apertures independently of the glrder and provided with heads seated in the recesses as set forth and shown.
